Warranty Registration

Congratulations on purchasing a new Sentinel Dehumidifier. Your new dehumidifier comes with an extensive warranty plan. To register, simply fill out and return the warranty form provided in the dehumidfier box.
Be sure to note your dehumidifier serial number as you will need it for registration.

Safety Notes

• The Sentinel Series Dehumidifier must always be connected using a grounded electrical connection (as required for all electrical appliances). If non-grounded wiring is used, all I iability reverts to owner and the warranty is voided .
• Sentinel Dehumidifiers should only be maintained and repaired by a qualified technician .
• Sentinel Dehumidifiers are only intended for operation when oriented with the unit sitting on its feet and level. Operating the unit in any other orientation could allow water to flood electrical components .
• Always unplug dehumidifier before moving .
• If there is a chance that water flooded the dehumidifier, it should be opened and allowed to dry thoroughly before reconnecting to electrical power and restarting .
• To ensure proper operation, neither the inlet nor discharge should be positioned against a wall. The inlet requires a minimum of 6′ clearance and the discharge requires a minimum of 36″ clearance.
• The best option for proper diffusion of air throughout the room is to have the discharge blowing away from a wall and the inlet pulling air in parallel to a wall.
• Do not insert your fingers or any object into the inlet or discharge.
• All work on the dehumidifier should be done with the unit “off’ and unplugged.
• Do not use water to clean the exterior of the machine. To clean unit, unplug from power, then use a damp cloth to wipe exterior.
• Do not stand on the machine or use it as a device to hang clothes.

Identification

• For future reference, write down the model, serial number, and date of purchase for your dehumidifier. This is extremely helpful if you need to seek assistance in the future.
• The data label on the side of your unit has the key characteristics of your specific machine.

Electrical Supply

• Power Supply: 115 V, 60 Hz AC, Single Phase
• Outlet Requirement: 3-Prong, GFI
• Circuit Protector: 15 Amp
• WARNING 40 Volts AC may cause serious injury from electric shock. To reduce the risk of injury:

1. Disconnect electrical power before servicing.
2. Only plug the unit into the grounded electrical circuit.
3. Do not use an extension cord.
4. Do not use a plug adapter.

Principle of Operation

• The Sentinel Series Dehumidifier utilizes its integral humidistat to monitor the conditioned space. When the relative humidity goes above the selected set point, the dehumidifier will energize. Air is drawn across an evaporator coil, which is cooler than the dew point of the air. This means moisture will condense out of the air. The air is then reheated through the condenser coil and distributed back into the room.

Installation

• The area to be controlled should be sealed with a vapor barrier. If the unit is installed in a crawlspace, all vents should be sealed.
• WARNING Do not install your dehumidifier in a corrosive environment. Some liquid vapor barriers dry via “solvent evaporation”. Always make sure that the barrier is completely dry and
  the area is thoroughly ventilated before installing a dehumidifier.

Step #1: Place the dehumidifier on a level surface.

• Do not place it directly on the vapor barrier. For example, use blocks, or pavers to create a level surface.
• If the unit is handled in such a manner that the compressor did not remain in the upright position, it is necessary to place it on a level surface and wait a minimum of 2 hours before turning the unit “on”
• NOTE: The dehumidifier can’t sit directly on the floor unless the unit is feeding directly into a sump pump next to it. Elevation is required to allow gravity flow of the condensate water drain.

Step #2: Set Up the Drain Line

• The drain line should be routed to a suitable drain on the outside. It must flow down to a drain without any loops, dips, or valleys.

Recommended Drain Option-Transition to PVC Pipe

1. Cut a piece of 3/4″ OD PVC that is approx. 6″ long.
2. Insert PVC into a 3/4″ elbow, then attach to a 3/4″ OD length of PVC to drain. (Note: Keep the length of the PVC drain pipe to a minimum).
3. Insert the open end of the tubing into the 3/4″ pipe so that it does not extend into the elbow fitting. For proper flow, a minimum downward slope of 1″ per 10′ run is required. (Note: If a proper downward angle is not possible, then it is recommended to use a Sentinel HDi90 which includes an integrated pump. Alternatively, you can use an external condensate pump).
4. Support the PVC tubing so that it maintains a smooth downward flow to the drain.
5. Always test the drain before leaving the installation area.

Step #3: Plug the unit into the 15 amp grounded circuit.

Key Functions

1. Power Key
2. Use this button to turn the dehumidifier on and off. Press once to turn the machine on. You will hear 2 beeps and the light will illuminate green. Press the power button a second time and you will hear one beep as the machine shuts down. Note that there is a one-minute fan delay on shut -down.
3. Arrow Buttons
   • Use the up and down arrow buttons to set the desired humidity setpoint on the display screen.
   • The set point can be any number between 36-90%. Creating a setpoint means that when the indoor humidity is lower than the set point, the machine will stop automatically. Conversely, when the indoor humidity is higher than the set level, the unit will operate.
   • NOTE: The humid levels displayed are approximate only(+/- 5%)
4. Continuous Mode
   • To switch into continuous mode, simply use the down arrow to set the humidity below 36%. The Cont. light should illuminate green on the display board to indicate that you have successfully switched into continuous mode.
   • The display screen will show “CO”.
   • When set to continuous, the dehumidifier will run constantly, regardless of the humidity level. To stop the machine, turn the unit off or switch back to normal humidistat operation. If you would like to switch back to normal humidistat operation, simply move the setpoint above 36%.
5. Central Control
   • This model is not applicable to the Sentinel HD55 / Sentinel HD55S.
   • The central Control light should be off at all times when not connected to the AC.
6. Auxiliary Terminals A5/A6
   • The A5/A6 on the terminal strip can be used as a water level warning switch for external condensate pumps.
   • If an external pump is connected, the pump must have a self-contained power supply and a water level signal line.

Indicator Lights

Humidity Display Screen

The display screen has two functions:

1. When the unit is powered on, it shows the humidity of the space.
2. While setting the desired humidity level, the screen will show the set humidity. After a brief delay, the display will revert to the current humidity level.

Power Indicator Light

• This light indicates that the unit is properly powered on and ready to operate. Always make sure the unit is “off’ prior to performing any service.
• When the power light is blinking, it means that the unit has reached the humidity setpoint.

Continuous Mode/Auto Defrost Light

• When this light illuminates green, it indicates that the dehumidifier is set to continuous operation mode.
• When the light glows red, it means the unit is in auto-defrost mode and clearing the evaporator coil of any ice buildup.

Compressor Light

• When the compressor light glows red, it indicates the compressor has been initiated but is currently warming up.
• Once the compressor light switches to green, it indicates the compressor is in working status.

Remote Control Instructions

• Sentinel Dehumidifiers can be controlled using an optional remote accessory. The Sentinel Remote  Control connects to your Sentinel Series Dehumidifier via a 25′ CAT 5 cable.
• The remote control contains an integrated sensor that gives you multiple options for remotely controlling your unit, in addition to monitoring the conditions surrounding the dehumidifier.
• One application for the remote control is to install the dehumidifier in one room with the conditioned air ducted into a second room that contains the remote. For example, the dehumidifier could be installed in a laundry room and ducted into a living room.
• The remote would then be mounted in the living room so the remote sensor can control the humidity and provide easy controls for the user.
• Another useful application for the remote control is if the dehumidifier is in an area that’s difficult to access on a regular basis. For instance, if your dehumidifier is installed in your crawl space, the remote could be mounted in your living space or garage. This provides you with an easy way to monitor the dehumidifier.

1. On/Off (Power)Button
   • Press the on/off button and the machine will start running (one beep). Press the button again to turn the machine off.
2. Up Button / Down Button
   • Use the Up and Down arrow buttons to adjust the humidity level.
